The official reference point. Irish immigration uses €10,000 as its estimated cost of living for a student for one academic year. That is the figure the State works from and the figure you must evidence. Treat it as the floor.
What the rent data shows. The RTB and ESRI Rent Index is the official source. It is published quarterly with a lag, so the national and city figures below carry the quarter they refer to and a newer quarter may be available by the time you read this. Check the current release before budgeting. It measures standardised average rents for whole registered tenancies, not rooms in shared accommodation or purpose-built student accommodation beds. Use it as the market context that sets the floor under room prices.
Measure | Amount | Period |
| National, new tenancies | €1,839 per month | Q1 2026 |
| National, existing tenancies | €1,513 per month | Q1 2026 |
| Dublin City, new tenancies | €2,237 per month | Q3 2025 |
| Galway City, new tenancies | €1,888 per month | Q3 2025 |
| Cork City, new tenancies | €1,753 per month | Q3 2025 |
| Dublin City, existing tenancies | €1,875 per month | Q4 2025 |
| Cork City, existing tenancies | €1,413 per month | Q4 2025 |
| Galway City, existing tenancies | €1,409 per month | Q4 2025 |
The regional cost advantage is narrowing
New tenancy rents rose sharply in Q1 2026 after rent rules changed on 1 March 2026. Year-on-year new tenancy inflation ran at 20.9% in Limerick city, 16.3% in Cork city, 13.3% in Galway city and 10.7% in Waterford city, against 8.3% in Dublin.
The absolute gap still favours the regional cities. Dublin City new tenancy rent was €350 per month above Galway City and €484 above Cork City in Q3 2025. But the gap is closing rather than widening.
As a new arrival you sign a new tenancy, so you pay the new tenancy rate, which is the higher one. In Q4 2025, Limerick City showed a gap of 49.7%, or €603 per month, between new and existing tenancy rents.
Choosing a regional city over Dublin remains defensible on cost and clearly better on availability. It is no longer the dramatic saving older content implies, and it should be weighed against the job market concentration in Section 3.3.
